VALVE-CONTROLLING MECHANISM.

To all whom, it may concern:

Be it knownthat I, JOSEPH L. EDLAND, a citizen of the United States, and a resident of Bloomfield, in the county of Essex and State of New Jersey, have invented anew and Improved Valve-Controlling Mechanism, of which the followingis a full, clear, and exact description. l This invention relates to certain improvements in valve-controlling mechanism, and the object of the'invention'is to, so control a plurality of valves that they may operate independently, yet in their operation will permit the passage of equal amounts of fluid. The invention relates particularly to auto matic valves operated by variations in the fluid pressure, and the invention is particularly useful in cases where it is desired to deliver a fluid from a common reservoir or passage past a plurality of separate valves. By way. of illustration, the invention may be considered as applied to a multiple cylinder internal combustion engine, and in this case the separate inlet valves of'the several cylinders would be automatically opened in succession by suction pressure. The utilization of my invention insures the opening of the several valves to exactly the same extent, so that the same amount of gas, air, vapor or explosive mixture delivered to one cylinder u on the opening of its inlet valve, will be elivered to each of the other cylinders upon the opening of their inlet valves. r

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in both the figures, and in which-- T Figure 1 is a central longitudinal section through a portion of two cylinder heads, showing the inlet valves controlled by mech anism constructed in accordance with my invention; and Fig. 2 is a top plan view of the parts'shown in Fig. 1, a portion of the conduit being broken away.

The invention is illustrated as applied to a two-cylinder internal combustion engine in which the air, gas, vapor or explosive mixture, is delivered through a conduit 10 from a carburetor or any other suit-able source to the two engine cylinders 11 and 12. The conduit 10 has two branches 13 and 14 leading to the inlet ports of the two cylin- J ders and theseinlet orts are controlled by Specification of Letters Patent. Application filed June 10, 1910.

corresponding valves 15- and 16. The-valves illustrated are of the puppet type and move inwardly against spring pressure during the suction strokes of their corresponding en ginepistons. In common practice, each of these inlet valves is provided with its own the same tension on two independent springs,

and as the parts become worn the difference will increase, so that often a far greater tension is exerted on one valve than on another, even though both valves control the supply to similar cylinders. I I

In my improved construction, I provide an equalizing mechanism, so that at any and all times one valve will be held against its seat with exactly the same force as is each of the other valves controlled by said mecha-. nisln.

In the specific form illustrated, I provide a rock shaft 17, extending transversely of the twobranches l3and 14, adjacent their intersection, and mounted in suitable bearings. This rock shafthas two arms 18 and 19 of equal length and disposed substantially at an angle of ninety. degrees to each other.; One arm 18' is connected to the valve 15 by'a spring 20, while the other arm 19 is connectedby a similar spring 21 to the valve 16. The rockshaft 17 is free to turn so that as the valve opens, the opening movement will be resisted, not simply by its own spring, but by both of the springs acting in series. As the rock shaft is between the two valves and the arms 18 and 19 extend substantially at right angles to the directions of movement of their corresponding valves, the rocking of the shaft will exert a substantially straight pull upon the valve stems. In Fig. 1, I have illus trated the .valve 16 as being partially open under the suction pressure exerted during the suction stroke of the piston in the cylinder l2, and it will be noted that when this valve is open, the rock shaftis tilted so as to distribute the strain equally upon the two springs.

By means of my invention, equal charges the cylinders from a common source or-reoeptacle, and this delivery of equal charges I conduit having a plurality of outlets, valves controlling said outlets, a series of spring connections within said\conduit one for each valve, said connections tending to hold all of said valves in predetermined positions and a rock shaft formed with a'pair of projections for receiving one end of each-0f said springs whereby the tensionof the springs is varied as the rock shaft is, moved.

2. In an internal combustion engine, a conduit having a plurality of outlets, valvescontrolling each of said outlets, a rock shaft having a plurality of arms projecting therefrom positioned above said outlets, and a spring connection between each of said valves and one of said arms whereby said valves are held in a predetermined position.

3. In an internal combustion pngine, a conduit having a plurality of outlets, valves positioned in and adapted to close each of outlets, a rock shaft positioned adjacent said outlets, arms projecting from opposite sides of said shaft, and a spring connection between each of said arms and one of said valves, whereby said valves arelreld in a predetermined position.

4:. In an internal combustion engine, a conduit having a pair of outlets, a pair of valves, one for each outlet, a rock shaft having apair of arms rigidly mounted thereon, and a pair of springs, each spring forming the sole connection between one of said arms and the adjacent'valvc.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
